In no particular order:
1) You’re one of the most amazing people ever; I’m happy to have met you
2) I wish I knew what to say to you. And I wish I had the guts to say it.
3) Get over him. Get over yourself.
4) I’m going to miss you next year.
5) You left too soon. We were just getting to the good part.
6) You always had my back, even when I was worried you wouldn’t. Thanks.
Awww, thanks! I <3 you too! =]
